Help with continuos firing

Hi!

I was trying to create a flamethrower that just spammed small fireballs while the right click is pressed.

I couldn't find the way to to I'd with right click so I tried to do Io with another key. I created a keybind that made it so if tab the global variable of type "Player_lifetime" (default: false) changed to true and if tab was released it changed to false. I then created a procedure that contains these blocks:

(No additional trigger)

If Get logic variable global:"variable name" = true and item in main hand of entity/target entity = (flamethrower)

Then shoot fireball of type small fireball ...
